To investigate the effects of 50 MHz radiofrequency irradiation on the calcium-ion efflux from avian brain tissue in vitro.
After decapitation chick forebrain was removed, followed by a labeling period with radioactive calcium solution which was aspirated by the tissue.
Modulation type: AM
Exposure duration: continuous for 20 min
|Exposure duration||continuous for 20 min|
|Modulation frequency||16 Hz|
|Modulation depth||95 %|
|Setup||Tissue samples were held in polycarbonate racks which were placed on either side of the transmission line`s center conductor.|
|Additional info||A foamed polystyrene chamber maintained at 37°C housed the transmission line. Control samples were placed on shelves with the chamber adjecent to the transmission line maintained at the same temperature.|
|power density||3.7 W/m²||minimum||measured||-||0.72 mW/cm², 1.44 mW/cm², 1.67 mW/cm², 2.17 mW/cm², 3.64 mW/cm² and 4.32 mW/cm²|
A statistically significant increase of calcium-ion efflux was observed at power densities of 1.44, 1.67, and 3,64 mW/cm2.
